Definition
The suction anchors are usually cylindrical units with large diameter (D of 3–8 m), open at the bottom and closed at the top, and generally with an aspect ratio (length to diameter, L/D) of two to six. The anchoring line is connected to the padeye attached to the side of the caisson at a depth down the mudline. The capacity of suction anchor is therefore the ability to resist the permanent and environmental loading from the anchor line during the operational conditions.
Failure Mechanism
The capacity of suction anchor is highly dependence of soil plasticity flow around the foundation. Many influential factors, especially for the complicated boundary conditions, such as anchor geometry, type of mooring system (loading direction and magnitude), installation performance, soil conditions, time after installation, durations of applied sustained loading, cycles of loading, etc., should be explicitly accounted for to investigate the failure mechanism.
